Answer:
the fuel efficiency in kilometers per liter is 16.561 kilometer per liter
Explanation:
The computation of the full efficiency in kilometers per liter is shown below:
39.0 miles ÷ gallon = (39.0 miles ÷ gallon) × (1.6094 km ÷ 1 miles) × (1 gallon ÷ 3.79 L)
Now cut the opposite miles and gallons
So, the fuel efficiency would be
= 16.561 kilometers per liter
Hence, the fuel efficiency in kilometers per liter is 16.561 kilometer per liter
Answer:
Vinegar has 4.09% of acetic acid.
Explanation:
The neutralization reaction is:
Each mol of KOH reacts with each mole of acetic acid so the quantity of moles of acetic acid is:
The mass of acetic acid is:
0.01702 mol×60.02g/mol=1.0215 g Acetic Acid
Finally, the percentage is:
%=1.0215 g Acetic Acid÷25g vinegar(solution)=4.09%
Answer:
a
Explanation:
Because that is the answer
Answer:
There are no unpaired electrons.
Explanation:
There are no unpaired electrons in the Lewis symbol for a nitride ion().The nitride ion has a charge of -3. The negative charge on the Nitride ion indicates a gain in electrons . Nitrogen has 5 valence electrons that is the number of electrons that are in its outer shell .The total number of electrons that the nitride ion has is equal to 5+3 = 8 electrons . Electrons usually appear in pairs and obey the octet rule therefore the nitride ion has four electron pairs no unpaired electrons.
Answer:
The side with lots of H+ and low pH
Explanation:
Because one of the feature of an acid is the ability to dissociate to H+.
And it has lower pH because the concentration of H+ is more than OH-
